5. Installation Instructions
Follow these steps to replace the carbon brushes in your compatible table saw. The exact procedure may vary slightly depending on your specific tool model, but the general principles remain the same.
- Prepare the Tool: Ensure the table saw is completely unplugged from the power outlet. Clear the work area and place the tool on a stable surface.
- Locate Brush Caps: Carbon brushes are typically housed in brush caps on the motor casing. These caps are usually plastic or metal and can be identified by a slot for a screwdriver or a hexagonal shape for a wrench. There are usually two brush caps, one for each brush.
- Remove Old Brushes:
- Carefully unscrew or unclip the brush cap.
- Gently pull out the old carbon brush. Note its orientation and how the spring is positioned.
- Inspect the old brush for wear. If it is significantly shorter than a new brush or chipped, it needs replacement.

- Install New Brushes:
- Insert the new YOKAMU carbon brush into the brush holder. Ensure the carbon block slides smoothly into its channel.
- Make sure the spring is properly seated behind the carbon block, applying pressure to push the brush against the commutator.
- Carefully replace and secure the brush cap. Do not overtighten.

- Test the Tool: Once both brushes are replaced and secured, plug the tool back into the power source. Briefly run the tool to ensure proper operation. It is normal for new brushes to spark slightly more than old ones during the initial break-in period. This should subside after a few minutes of use.
6. Maintenance
Regular inspection of carbon brushes can extend the life of your power tool and prevent unexpected failures.
- Periodic Inspection: Depending on tool usage, inspect the carbon brushes every 50-100 hours of operation.
- Check for Wear: Replace brushes when they are worn down to approximately one-quarter of their original length, or if they show signs of chipping or uneven wear.
- Commutator Condition: While inspecting brushes, also check the commutator for excessive scoring or discoloration. A clean commutator ensures optimal brush contact.
7. Troubleshooting
If your power tool exhibits issues after carbon brush replacement, consider the following:
| Symptom | Possible Cause | Solution |
|---|---|---|
| Motor not starting or intermittent operation | Brushes not fully seated, damaged brushes, or incorrect brush type. | Re-seat brushes, inspect for damage, ensure correct part number. |
| Excessive sparking at the motor | Brushes not properly broken in, worn commutator, or incorrect brush material. | Allow for break-in period (a few minutes of light use). If persistent, inspect commutator or consult a professional. |
| Reduced motor power or overheating | Brushes not making full contact, or other internal motor issues. | Verify brush installation. If problem persists, professional inspection is recommended. |
If troubleshooting steps do not resolve the issue, discontinue use and consult a qualified technician or contact YOKAMU customer support.
